You stated that unemployment is driven by demand. You also stated that there's no evidence unemployment is driven by a mismatch between the pattern of demanded skills vs. the pattern of present skills.
I am not arguing with you about these claims. I am just going on what you say to me. The combination of those claims LOGICALLY ENTAILS that unemployment, being driven by weak demand in every sector, and NOT just by weak demand for certain skills in specific sectors, MUST be driven by weak demand for labor overall, across sectors; in other words, every single sector does not need any more labor of any kind.
This is what you actually said. If you didn't mean it, then you should have said something else.
What I said... which is true... is that this is an extreme claim, and eminently testable. And you still haven't provided any test of it. Although you seem to expect me to believe it. So rather than linking to Krugman again... why don't you provide evidence for the extreme claims you are making?
By the way... I am a regular reader of Krugman's because I like a lot of what he says, so if you cannot be "clear enough" and cannot defend your extreme claims to a Krugman fan, then the problem isn't that you are being discriminated against on the basis of ideology. It is that you are making bold claims which have certain entailments, you are refusing to recognize these entailments and you are refusing to provide evidence to support the claims at the same time as you refuse to withdraw them.
